Hi
I am having the following code:

Code:

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.DataInputStream;
import java.io.FileInputStream;
import java.io.FileWriter;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

public class ReadLogFile {

	/**
	 * @param args
	 */
	public ReadLogFile(){
		
	}
	private List readFile (String inputFile,String content){
		List logs = new ArrayList();
		try {
			FileInputStream fis=new FileInputStream(inputFile);
			DataInputStream dis=new DataInputStream(fis);
			BufferedReader br=new BufferedReader(new InputStreamReader(dis));
			String strLine;
			while ((strLine = br.readLine()) != null) {
				System.out.println("Line:|" +strLine);
				int index;
				index = strLine.indexOf(content);
				System.out.println("Index:|" +index);
				if (index != -1){
					System.out.println("log with search string:|" +strLine+"|");
					logs.add(strLine);
				}else 
					System.out.println("line does not have serach string");
			}
			
		}catch (Exception e){
			System.out.println("Exception while reading file:|" +e.getMessage());
		}
		return logs;
	}
	
	private void writeFile(List logs,String outputFile){
		try {
			BufferedWriter bw = new BufferedWriter(new FileWriter(outputFile,true));			
			System.out.println("Inside write file method,list size:|" +logs.size());
			for(int i=0;i<logs.size();i++){
				System.out.println("Inside for loop:|" );
				bw.write((String)logs.get(i));
				bw.newLine();
				System.out.println("file has been written successfully:|" +logs.get(i) );
			}
			bw.close();
		}catch(Exception e){
			System.out.println("Exception when writing the file:|" +e.getMessage());
		}
		
	}
	
	
	public static void main(String args[]) throws Exception{
		// TODO Auto-generated method stub		
		String inputFile = null;
		String searchString = null;
		String outputFile = null;
		System.out.print("Enter Input File: ");
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		inputFile = br.readLine();		
		System.out.print("Enter Search String: ");
		BufferedReader br1 = new BufferedReader(new InputStreamReader(System.in));
		searchString = br1.readLine();		
		System.out.print("Enter Output File: ");
		BufferedReader br2 = new BufferedReader(new InputStreamReader(System.in));
		outputFile = br2.readLine();		
		ReadLogFile logfile = new ReadLogFile();
		List log = new ArrayList();
		log = logfile.readFile(inputFile,searchString);
		System.out.println("Reading log file completed:|");
		logfile.writeFile(log,outputFile);
	}
}

I need to search a string and write to new file

The string here is date 10-10-2008

Input file
Date Time Server IP Desc
---------------------------------------------------------------
10-10-2008 10:10 Server 1 xx.xx.xx.xx File Server
11-10-2008 20:10 Server 2 xx.xx.xx.xx File Server Linux
12-10-2008 22:10 Server 3 xx.xx.xx.xx File Server Win
13-10-2008 23:10 Server 4 xx.xx.xx.xx File Server aaa

OutPut File
10-10-2008 10:10 Server 1 xx.xx.xx.xx File Server

The current code will write the whole line into a new file when i give a date.
I need more than 2,3 dates to be searched and lines written to new file.

I dont know how to edit

Please help

Thanks in advance.
